General Notes

Henry III (of Castile and León) (1379-1406), king of Castile and León
(1390-1406), the son and successor of King John I. Although at the beginning
of his reign the country was plagued with continual disorder and violent
anti-Semitism, Henry was soon able to placate the nobility and restore royal
authority. He won victories over the English at sea, and the conquest of the
Canary Islands began under his sponsorship in 1402.
